Making a material array is rather easy. You make a shape, then you will create a material array. Now, the hard part was actually finding the best settings. I wasted about 10 of these tags trying to get the best colors, but I finally did and wanted to share them with all of you.

These were ones that I found on Amazon, but xTool makes some, and so do other retailers. They are rather small, so if you have a bigger one, make sure to fill up the whole piece.

Now it’s laser time. This is a rather short laser engraving. Just make sure that you wear your laser safety glasses and don’t pick up the coin, no matter how tempting, or you will burn yourself. I'm also not going to attach the material settings as there are just too many.

Good news, you're done, and this will surely help you find the right colors.
